Rarest things in chess.

What are some of the rarest things in chess? I will name some:

Hikaru Nakamura spending more than 10 seconds on a move in online chess

OTB chess tournaments happening in Delaware, USA

Managing to beat Magnus Carlsen

Please list of some more rare things.

Variations that I studied actually occurring in a game.

Check mate in very first move 😜

Predicting your opponents next move correctly.

triple check

As white, players at my level playing anything in the 2... d6 Open Sicilian besides the Bowdler Attack.

Hexapled pawns

I think bishop and knight vs. king (no pawns) endgame is quite rare...

Happened to me one time in I guess over 14,000 games (including lichess account)...

I actually won this endgame vs. stockfish one time but I still don't really know how to do it, it was lucky...  

Fortresses and stalemates at gm leverl ig

dude thats not rare its impossible

Triple check is also impossible

Its a joke

tripled pawns

Thats (pretty much) already been said. https://www.chess.com/forum/view/fun-with-chess/rarest-things-in-chess?newCommentCount=1&page=1#comment-62887757

Beat stockfish 14 wihout any bot
